A display panel, and a thin film transistor device and a manufacturing method thereof. The manufacturing method comprises: forming a metal film layer on a top surface of a transparent substrate; patterning the metal film layer to form a gate pattern layer; performing planarization processing of the gate pattern layer by forming a patterned nanofiller-containing planarization layer; and forming, on the top surface of the transparent substrate, a gate insulation layer, a semiconductor layer, a source/drain electrode layer, a passivation layer and a pixel electrode layer.
